Hey guys I have a 2007 335i and last week two of my injectors went out and was wondering if you guys think If I should just replace all of them together or just the ones that went out

Also wanted to see which ones you guys went with either index 11 or higher if there is anything higher then 11 since the stock ones come with index 10 I believe

Any advice would be appreciated if you guys have gone through replacing your injectors your input would make it a lot easier since it is an expensive job thank you!

Well I believe the newest revision are index 13 injectors now.
I've been seeing a lot of brand new (6) Index 12 injectors for $900 so you could get those too.

You have to make sure each bank of three cylinders has the same index. Although, I have seen some people say you can mix 11 and 12 but I cannot confirm.

For example, I checked the injectors on my 2008 and the front three are index 12 and the rear bank are index 11.

You will need to code the new injectors as well.

newest index is 12

sucks to fork the bill, but if 2 went, it's only a matter of time, get em all done at once if it is feasible.
